As an educator or non-profit employee, your 403(b) retirement plan likely offers both annuity and mutual fund options. Having helped hundreds of teachers navigate this exact decision, I’ll break down the critical differences to help you make an informed choice that aligns with your financial goals.

Understanding Your 403(b) Investment Options
403(b) Annuities (Tax-Sheltered Annuities)
- Insurance products offered through providers like AXA, VALIC, or TIAA
- Guaranteed income options in retirement
- Principal protection features available (for a cost)
- Higher fees (typically 2-3% annually)
403(b) Mutual Funds (Custodial Accounts)
- Market-based investments through firms like Vanguard or Fidelity
- No income guarantees – returns depend on market performance
- Lower fees (often 0.03%-0.50% for index funds)
- Greater flexibility in accessing funds
Key Differences at a Glance

| Growth Potential | Capped (fixed/indexed) or market-based (variable) | Uncapped (follows market) |
| Guarantees | Possible minimum returns/income | None |
| Liquidity | Limited (surrender periods) | High |
| Best For | Those prioritizing safety over growth | Those comfortable with market risk |
Cost Comparison: The Hidden Drag on Returns
Let’s examine how fees impact a $50,000 investment over 30 years at 7% growth:
Annuity (2.5% fees):
FV = 50,000 × (1 + 0.07 - 0.025)^{30} = \$216,097Mutual Fund (0.10% fees):
FV = 50,000 × (1 + 0.07 - 0.001)^{30} = \$380,613Difference: $164,516 lost to higher annuity fees
When an Annuity Might Make Sense
Consider annuities only if:
- You’re within 10 years of retirement
- You absolutely cannot tolerate market volatility
- You’ve maxed out other retirement accounts
- You want predictable lifetime income
Even then, limit annuity allocation to 10-30% of portfolio.
Why Mutual Funds Usually Win
For most educators, mutual funds offer:
- Lower costs = more money stays invested
- Better long-term growth potential
- More flexibility with withdrawals
- Simpler products without complex contracts
Common 403(b) Pitfalls to Avoid
- Paying excessive fees without realizing it
- Over-allocating to annuities too early
- Not using index funds when available
- Ignoring the 403(b)(7) custodial option
Sample Allocation Strategies
For Young Educators (20s-40s)
- 90-100% mutual funds (diversified index funds)
- 0-10% bonds
- 0% annuities
Mid-Career (40s-50s)
- 70-80% mutual funds
- 20-30% bonds
- 0-10% annuities
Near Retirement (55+)
- 50-60% mutual funds
- 20-30% bonds
- 10-20% annuities (if desired)
Action Plan: Optimizing Your 403(b)
- Identify your current investments (call your provider if unsure)
- Calculate your total fees (look for expense ratios + additional charges)
- Shift to lower-cost options if available
- Consider moving old annuities to mutual funds if surrender period ended
- Rebalance annually to maintain target allocation
Final Recommendation
For most educators, building your 403(b) around low-cost mutual funds will yield better long-term results than annuities. The cost difference alone can mean hundreds of thousands more in retirement savings. While annuities have their place for those nearing retirement who want income guarantees, they’re generally not the best choice for younger educators focused on growth.
